Female mate preference for males displaying costly traits is a puzzling phenomenon found in nature. Fisher was the first to propose a formal model describing this paradoxical system of sexual selection. Despite the many models constructed from his theory, much remains unknown about its mechanics, especially in different genetic settings. Through simulations, Veller et al. compared population dynamics between haploids and diploids and found that Fisherian sexual selection acts differently on diploids compared to haploids due to linkage mechanisms.

文摘：区分单倍体和二倍体之间的费舍尔性选择动态

雌性对表现出昂贵特征的雄性的偏好是一种在自然界中发现的令人费解的现象。费舍尔是第一个提出正式模型来描述这种矛盾的性选择系统的人。尽管根据他的理论构建了许多模型，但对其机制仍有很多未知，尤其是在不同的遗传环境中。通过模拟，Veller 等人。比较了单倍体和二倍体之间的种群动态，发现由于连锁机制，Fisherian 性选择对二倍体和单倍体的作用不同。
